Pin Definition

The RAK15007 WisBlock 1MByte FRAM Module comprises a standard WisBlock connector. The WisBlock connector allows the RAK15007 module to be mounted to a WisBlock Base board. The pin order of the connector and the pinout definition are shown in Figure 3.

Figure 3755: RAK15007 WisBlock FRAM Module Pinout Diagram

The WisBlock Sensor connector is used to this module and the IO used for WP pin at Pin 12 will depend on where sensor slot the module is plugged in. The table shows the compatible pins used by different sensor slots:

WP (Write Protect Pin)

Slot A	Slot C	Slot D	Slot E	Slot F
IO1	IO3	IO5	IO4	IO6

NOTE

RAK15007 should not be plugged in Slot B as it is dedicated for IO2 (WisBlock IO2 pin) that controls the 3V3_S voltage output.
